Detectons involving more than one individual, but part of the same social unit, e.g., mother and young, were counted as a single event. Encounter rates were derived by dividing the number of notonally independent events by the camera-trap-nights × 100. Results A total of 3,510 trap-nights yielded 187 notonally independent photographs of 11 species namely: Jungle Cat Felis chaus, Leopard Cat Prionailurus bengalensis, a & Rusty-spoted Cat P. rubiginosus (27 notonally independent photographs), Small Indian Civet Viverricula indica (46),
